SPECIFICATION forming part of Letters Patent No. 624,580, dated May `9, 1899.

Application iiled January 29,` 1898. Serial No. 668,376. (No model.)

T0 all whom, t may concern:

Be it known that I, WILLIAM G. TOUSEY, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Water-Filters, of which the following is a full, clear, and exact descrip tion.

My invention relates to improvements in" filtering-machines; and the objects-aimed at are, first, superior filtration; second, prod longed efficacy of the filtering media, and, third, Ininimu In requirement of attention and care. l attain these results by the mechanism illustrated in the accompanyingdrawings, in which- Figure l is a vertical section of the entire machine through the line @c in Fig. 2. Fig. 2 is a horizontal section through the line y y in Fig. l. Fig. 3 is a vertical section of the machine, showing a modified form with filter# ing-tube T, its plug t', the supporting-plate G, and charcoal surrounding the filteringtube. Fig. 4 is a detailed top view of the member G on, an enlarged scale. Fig. 5 shows the elongated hood as fixed to the member D. Fig. G shows a sectional View of a portion of the filtering-disk F and the water-proofing solutionf, applied to its margin.

The filter-case consists, as will be seen, of the segments A H K, clamped together by the screw M in the swinging yoke L. When,A

however, the segment H is dispensed with, the segment K is made by suitable modification to engage with segment A, and`the segments are clamped together by the screw M, set in the yoke L, suitably modified.

A is the uppermost segment'of the filter, having the inlet B, the waste-cond uit dzfwith its outlet-valve l?, the ears a3, andthe flange I having the shoulder h, fitting against the per forated plate G in opposition to the liange et.

h is a duct leading from a channel between the flange a and the rim h5 and is designed to conduct any drip from the joint between the flange d and the shoulder 7L to the interior of the filter-case. This duct is designed, primarily, for the combination in which the charcoal-chamber H is dispensed with, and the segment K, suitably modified, is attached directly to segment A, as elsewhere set forth. When, however, a filtering medium is elnployed in segment H so compact as to produce pressure and backflow-the duct h is K is the lowermost segment of the filter.-

It has the flange 7.a, opposed to the shoulder h3, and supports the plate G', with the lteringdisk F'. duct 762, designedto collect and conduct any leakage of the filter-joints to the interior of the filter-case.

K is the outlet of the finished filtrate. This outlet K is made large enough to prevent pressure in the segment K and consequent lbackflow through the duct 7a2.

L is a swinging yoke supported by the ears a3. in place.

The unfiltered water enters under pressure through the inlet-pipe B, passes into the small reactionary motor-wheel D, and issues thence through the orifices d3 d. It is then forced `through the filtering-disk F, which rests on the perforated plate. G. This filtering-disk removes all matter held in suspension. For

this disk I ordinarily prefer felted cotton fiber, properly sterilized, `but under some conditions would use porous stone, filter-paper, or unglazed porcelain, as circumstances might indicate.

It has also the channel 7a3, with 'thel The screw-heads Z serve to hold the yoke -This feature of the filter is esteemed of much 'importance as providing effectively against Waiving for a moment the description of the device by which the filtering-disk is cleaned and the chamber in which it is held is iiushed, let me point out the further operations to which the Water undergoing filtration is subjected. Passingth rough the perforated plate G it enters the section H, which carries the charcoal J, as in Fig. 1, or filtering-tubes and charcoal, as in Fig. 3, or in some instances filtering-tubes without the charcoal. Charcoal, as is well known, has a special power over obnoxious odors, tastes, and soluble coloring-matter; but as commonly employed this efficacy is soon lost. Worse than that, the bed is liable to become the nest and breeding-place of organisms inimical to health.. By my device of an antecedent filterchamber I abstract all suspended matter from the waterand so protect the charcoal bed, with its peculiar power of eliminating obnoxious elements, thus economizing and greatly prolonging its eicacy. After having been thus subjected to the action of the charcoal the filtrate passes on through the perforated plate G2 and the filtering-disk F', as in Fig. 1, or through the filtering-tubes T, as in Fig. 3.

an obvious danger. The filtrate at length issues from the outlet K' in a vhighly-refined condition, When the porcelain tubes T, Fig. l 3, are employed they are held firmly in posil tion by the perforated pl ugs t', attached to the plate G, as in Fig. 3. Unglazed porcelain, when combined of suitable materials, consti.- tutes one of the most highly esteemed filtering materials .that we have; but its practical use is attended with the grave disadvantage that it quickly clogs and requires frequent scouring. This scouring process is difficult, dirty, and attended with no little breakage. Now these disadvantages I overcome in a large measure by the protective action of the primary self-cleaning chamber A.

The self-cleaning device I will now return to and describe more fully.

D is a reactionary wheel revolving on the spindle c, which is supported by the transverse bar c.

d2 is a hollow stem or stump having bearings on the spindle e.

(Z are driving-arms.

d is a concentrating-orifice whence issues the scouring-jet.

E is an elongated hood fixed to the'member D and immediately above the orifice d'. This hood is intended to overarch the scouring-jet which issues from the orifice d', keep it intact, and hold it to close and contiuous action on the ltering-disk F.

E' is an arm designed vto carry one end of the sweep N when such a sweep is used.

CL2 is a waste canal or cond uit with an outlet-valve at P. This conduit is made to cling wasteconduit extending below the plane of the filtering-disk that disk is, when the,

chamberA is being flushed and the scouring process is in progress, drained of its load of superincumbent water and exposed to the direct and unembarrassed action of the scouring-jet which issues from the orifice d'. By opening the valve P the water is permitted to course with force into the motor-wheel D and to issue with energy from the contracted orifices d d. The kick of the terminal jets d causes the wheel to revolve on the spindle e, and the revolution of the wheel brings the scouring-jet d' to play successively over all parts of the disk F, thus effectively scouring its surface and flushing the chamber. concentrating the flow of water to the relatively small orifice d', I get a jet of great energy and cleansing power, and by attaching it to the revolving wheel I bring it to act in turn on all parts of the surface to be cleaned. Where circumstances require it, I reinforce the action of the scouring-jet by a sweep of chain N or other suitable material attachedto the member D, as shown in Fig. 2. After a brief interval the valveP is closed, and the machine will be found in condition to filter again freely.

Theseveral segments or chambers are made readily accessible for the renewing of the tiltering media bya slight retreat of the screw M and the swinging aside of the yoke L.

Where tjhe most highly refined results are called for, I combine the filtering-disk F, the Acharcoal bed J, and the filtering-disk F, or in lieu of F', the unglazed porcelain tube T, substantially as shown in Figs. l and 2. Under less exacting conditions I det-ach the primary self-cleaning segment A and use it,with suitable modifications of the yoke L and the part K, as an independent filter; or, again, underother requirements I dispense with the charcoal bed .I and the perforated plates G G2 and the filtering-disk F' and use porcelain tubes, as in Fig. 3, and as a result have a highly effective filter which is practically selfcleaning. Finally, I provide against lateral percolation through the filtering-disks F F and secure good and easily-made joints by dipping the margin of the filtering-disks in a waterproofing solution, as shown in Fig. 6. Accidental drip or leakage of the joints is provided for by the channel between the rim 7L and the fiange a, the channel las', and the ducts h 7a2, leading to the interior ofthe filter-case, as shown in Fig. l.
